I am trying to set up Tipfy extensions on a Python/Google App Engine project that I've been brought in on. I have followed all the instructions for running bootstrap.py and then bin/buildout. Everything seems to have worked but now when I try to import tipfy.ext.auth, I get this error:

I'm a bit lost now and don't really know where to even look for the solution to this as I am, admittedly, very new to both Python and GAE. Any help or direction on how to get this extension working would be greatly appreciated.
